As described above, the reagent bottle 100 according to the present embodiment can accommodate a plurality of different types of medicines and can transfer the medicines to the outside. Hereinafter, the reagent bottle 100 according to the present embodiment will be described in detail with reference to the drawings, taking as an example the case where the fluid medicine contained in the container is pumped to the outside by the bag valve 1.

Fig. 1A is a schematic view showing a reagent bottle 100 according to an example of the present embodiment; fig. 1B is an exploded view showing the reagent bottle 100 according to the example of the present embodiment.

In the present embodiment, referring to fig. 1A and 1B, the reagent bottle 100 may include a bottle body 110 and a bag valve 1. The bottle 110 has an opening 112 and an accommodating space 111 therein. The bag valve 1 may contain a medicament and may pump the medicament to the outside. A portion of the bag valve 1 may be received in the receiving space 111 of the bottle body 110, and the bag valve 1 is configured to seal an opening portion 112 of the bottle body 110 (described later). The bag valve 1 is configured to accommodate different kinds of medicaments, and the kind of the medicament it accommodates can be adjusted according to the user's needs.

In some examples, the medicament may be viscous.

In some examples, the bag valve 1 may include a container part 10 disposed in the receiving space 111 of the bottle body 110, and a material transfer mechanism 30 disposed on the container part 10 (see fig. 1A and 1B). The container portion 10 may have a plurality of containers for containing a medicament (described later). The material transfer mechanism 30 can transfer the medicine contained in the container portion 10 to the outside (described later).

In some examples, the material moving mechanism 30 may include an outfeed portion 90 (see fig. 1A). In some examples, outfeed portion 90 may be an aerosol spray head. In this case, the medicine can be ejected from the reagent bottle 100 in the form of a spray, so that the ejected medicine can obtain a large action area.

The reagent bottle 100 of the present embodiment will be described below by taking the discharge part 90 as a gas mist head as an example. In other words, in the present embodiment, the reagent bottle 100 transfers the medicine to the outside by the gas mist ejection method.

In some examples, as described above, the reagent bottle 100 may include a bottle body 110 (see fig. 1B).

The total volume of the container portion 10 is smaller than the volume of the accommodating space 111. In some examples, the receiving space 111 may be filled with a gas having a high pressure. The filled high pressure gas is located between the bottle body 110 and the container portion 10. In this case, the filled high pressure gas may form a positive pressure in the bottle body 110 to press the container portion 10, thereby assisting the material transfer mechanism 30 in transferring the medicine using the pressure. The pressure of the filled high pressure gas may be determined according to the related safety requirements and the pressure required to squeeze the fluid within the container portion 10.

In some examples, the vial 110 may be a hollow container having a cylindrical shape. The hollow portion of the bottle body 110 may form a receiving space 111. The bottle body 110 may have a circular opening at the top, i.e., the opening 112.

In some examples, the bottle body 110 may be an aluminum alloy steel cylinder or a carbon steel cylinder. The bottle 110 may be a welded cylinder or a seamless cylinder. In this case, the bottle body 110 can have sufficient strength to support the creation of a positive pressure in the bottle body 110.

In some examples, the opening portion 112 of the bottle body 110 may have an outwardly curved edge a, which may be configured to connect to the bag valve 1.

Fig. 2 is a sectional view showing the bag valve 1 according to the example of the present embodiment.

In some examples, the first member 33a may be spaced apart from the second member 33B to elongate the protruding shaft 33 (see fig. 3B). In this case, the first base 31 may be remote from the second base 32, so that the first fluid conduit 51 may be separated from the third fluid conduit 53, in other words, when the first fluid conduit 51 is not nested with the third fluid conduit 53.

In some examples, the first member 33a of the protruding shaft 33 may rotate relative to the second member 33 b. In this case, the second base body 32 can rotate relative to the first base body 31, in other words the third fluid duct 53 of the outfeed portion 90 can rotate relative to the second fluid duct 52. In some examples, the third fluid conduit 53 may rotate above the second fluid conduit 52 (see fig. 3C).

In some examples, the material moving mechanism 30 may have a second station (see fig. 3D). The first member 33a may be adjacent to the second member 33b to shorten the protruding shaft 33. In this case, the first base 31 may be close to the second base 32 such that the third fluid conduit 53 is sleeved outside the second fluid conduit 52, and when an external force is applied to the discharging part 90, the second valve 71b may be opened and the medicine in the second container 13 is transferred to the discharging part 90 by the positive gas pressure, thereby enabling the reagent bottle 100 to eject the medicine in the second container 13.
